Shingles, also known as herpes zoster, is an infection. It is the same varicella-zoster virus (VZV) that causes
chickenpox. Inactive copies of the virus live in your nerves. If these viruses become reactivated, then you get shingles.
If you haven’t had chickenpox and haven’t gotten the vaccine, then being around someone with shingles could lead to chickenpox.
It starts with a burning or tingling feeling. A rash with fluid-filled bumps will appear a few days later. These will crust over and dry out. It takes about 5 weeks to get better. In some people, there can be lasting pain in the site of the rash.
